Feeling defeated

I’m 26 - husband & I have a 4yo daughter. Been trying for a year for our 2nd & no luck. I was hopeful this go around... confirmed I was ovulating with test, got busy multiple times both days I was ovulating. I always have normal periods & wasn’t supposed to start for another week but I’m bleeding. I lightly spotted yesterday & was hoping it was sign of implantation but today the bleeding has increased like my regular period. I thought for sure this was going to be it! I also found out last year I have stage 1 endometriosis after a laparoscopic procedure. Not sure if this is making it harder for me. Need some encouragement.

Thanks for reading.
